Abstract
The embodiments disclosed herein reduce numerous active regulators (e.g., to only one) used in previous circuits that require regulated current and still accomplish the current regulation provided to each load by means of an array of autotransformers, and if required, rectifiers, and filters. Therefore, in an exemplary embodiment, there is eliminated the numerous active regulators by replacing them with simple passive components and an active regulator.
Claims5
A constant current circuit for driving a plurality of loads comprising:
- a current regulator;
- a first autotransformer coupled to the current regulator;
- the first autotransformer being divided into parts, wherein each of the parts has an inductance and the inductances are substantially equal, and
- a second autotransformer for receiving a first current from the first autotransformer and a third autotransformer for receiving a second current from the first autotransformer, wherein the first and second currents are substantially equal.
A constant current circuit for driving a plurality of loads comprising:
- a current regulator;
- a first autotransformer electrically coupled to the current regulator;
- said first autotransformer being divided into parts, wherein each of the parts has an inductance substantially equal to the respective inductances of the other parts;
- a second autotransformer for receiving a first current from the first autotransformer;
- a first load connected in series with the first autotransformer, with the first load being for receiving a second current;
- and
- the first and second currents being substantially equal.
